摘要： A photoelectric conversion device is provided with an electron emitter including a meta-surface emitting an electron in response to incidence of an electromagnetic wave. The meta-surface includes a plurality of photoelectric conversion units having a sensitivity for electromagnetic waves having mutually different wavelength regions. The plurality of photoelectric conversion units respectively include patterns having mutually different configurations.

摘要： In a photoelectric conversion device, the potential control unit controls electric potentials applied to the meta-surface. The meta-surface includes a plurality of patterns which are space away from each other. The plurality of patterns include an antenna portion and at least one bias portion. The antenna portion extends in a predetermined direction and emits the electron in response to incidence of the electromagnetic wave. The potential control unit switches a first state and a second state by controlling the electric potentials applied to the plurality of patterns. In the first state, a component of an electric field from the bias portion toward the antenna portion in a predetermined direction is positive. In the second state, a component of an electric field from the bias portion toward the antenna portion in the predetermined direction is negative.

摘要： In a photoelectric conversion device, the meta-surface includes a first antenna portion, a first bias portion, a second antenna portion, and a second bias portion. The first antenna portion extends in a first direction and emits an electron in response to incidence of the electromagnetic wave. The first bias portion faces the first antenna portion and is configured to generate an electric field having a component in the first direction between the first bias portion and the first antenna portion. The second antenna portion extends in a second direction intersecting the first direction and emits an electron in response to incidence of the electromagnetic wave. The second bias portion faces the second antenna portion and is configured to generate an electric field having a component in the second direction between the second bias portion and the second antenna portion.

摘要： In an electron tube 1, the meta-surface S emits an electron in response to an incidence of the electromagnetic wave. The first and second electrodes 81, 82 are spaced away from each other, and apply potentials different from each other to the meta-surface S. A holder 30 is disposed in the housing 10 and holds the electron emitter 20. A first conductive line 83 of the meta-surface S is electrically connected to the first electrode 81. A second conductive line 84 of the meta-surface S is spaced away from the first conductive line 83, and is electrically connected to the second electrode 82. The first conductive line 83 extends from the first electrode 81 to the second conductive line 84. The second conductive line 84 extends from the second electrode 82 to the first conductive line 83.
